Truma water heater 2E
i have this water heater fitted to my Motorhome I believe. This works ok at the start of use but if it's set to 40C the water heats up and as you use it does not appear to fire up and keep the water at this temperature.
If set to 60C again it works ok at start of use keeps the water 60 ok but after a few hours in use there is air in the system after the air is bled out via sink taps again works ok for a few hours are the air returns. I was like this the day I picked it
up the dealer gave me some story about using the heating at the same time as the hot water it will cause this. But I am sure if this persists it will damage the unit. I have tried to down load a diagram / drawning of the unit to see if there is any non return
valves fitted.
But this is not clear from the drawning I have found to date as I think if fitted this is leaking. so I just keep switching the unit on when hot water is required.
Any ideas welcome to solve this.
